Control of algae production will be necessary when lagoons are utilized as a preapplication treatment process for overland flow. The overland flow process has a surface discharge and must meet secondary treatment limitations to be viable. Brief summaries of other algae removal investigations are presented which do not show a relationship between operational and design criteria and discharge concentrations greater or less than the secondary treatment limits for total suspended solids. The data from an investigation conducted at the Robert S. Kerr Environmental Reserach Laboratory indicate both the number and species of algae in the applied wastewater control the ability of the overland flow process to meet secondary treatment limits for total suspended solids.
